measures the acidity or basicity of a solution
1-14
7 neutral
0 acidic
14 basic

Question 18

pH of 5

Answer 18

1 x 10 -5 = .00001

Question 19

acid deposition

Answer 19

type of air pollution that conatins nitrogen adn sulfuric acids that fall to the ground from the atmosphere as precipation or as dry acidic particles

Question 20

sources of N

Answer 20

cars

Question 21

sources of s

Answer 21

industries - burning coal

Question 22

pH of mormal rain

Answer 22

5-6 - because of dissolved CO2 in the air

Question 23

EFFECTS OF ACID RAIN

Answer 24

lake acidfication -decrease pH of water
corode 
fragile egg shells
forest deline - fragile seeds ruind bark
soil acidfication

Question 25

lake erie

Answer 25

not acidied because of limestone basin

Question 26

n based acid deposition

Answer 26

2NO2 + H2O - HNO3 + HNO2

Question 27

s based acid deposition

Answer 27

SO2 + O2 - SO3+SO3+ H2O - SO4

Question 28

where is ozone a pollutant

Answer 28

in troposphere

Question 29

what depletes the ozone

Answer 29

CFCs

Question 30

montreal protocol

Answer 30

international ban on CFCs to help ozone

Question 31

thermal inversion

Answer 31

a situation in which a layer of warm air (an inversion layer) lies over a layer of cool air. If an inversion occurs over a city, it results in air pollution, because some pollutants, such as smoke or soot, which are usually removed by normal weather processes, are held at the surface by the cool layer

Question 32

CFC equations

Answer 32

CL + O3 - CIO + O2 CIO + O - CL + O2 = O3 + O = 2O2

Question 33

photochemical smog

Answer 33

2 primary pollutants (NOx and hydrocarons from cars) -forms 2 secondary pollutant (O3 and PANs) needs UV energy - no wind = thermal inversions

Question 34

photochemical smog equation ozone

Answer 34

1). ozone production NO + O2 - NO2 NO2 + O2 + sun - NO + O2 + O O+ O2 - O3

Question 35

photochemical smog equation PANs

Answer 35

hydrocarbon + NO2 + O2 + sun - PANS

Question 36

industrial smog

Answer 36

unburned carbon from coal = soot | particulat ematter - black

Question 37

industrial smog equations

Answer 37

SO2 (coal) + H2O (air) - H2SO4 H2SO4 + NH3 (air) - NHSO4 (solid ammonia sulfate
